18. The Heads of the Proposals. 1647.—In the meanwhile Cromwell was doing his best to come to an understanding with Charles. A constitutional scheme, to which was given the name of The Heads of the Proposals, was drawn up by Ireton and presented in the name of the army to the king. It provided for a constant succession of biennial Parliaments with special powers over the appointment of officials, and it proposed to settle the religious difficulty by giving complete religious liberty to all except Roman Catholics. Those who chose to do so might submit to the jurisdiction of bishops, and those who chose to do so might submit to the jurisdiction of a presbytery; but no civil penalties were to be inflicted on those who objected either to Episcopacy or to Presbyterianism or to both.
19. The King's Flight to the Isle of Wight. 1647.—No proposals so wise and comprehensive had yet been made, but neither Charles nor the Parliament was inclined to accept them. Many of the Agitators, finding that there was still a Presbyterian majority in Parliament, talked of using force once more and of purging the Houses of all the members who had sat in them whilst the legitimate Speakers were absent. In the meanwhile the king grew more hostile to Cromwell every day, and entered secretly into a fresh negotiation with the Scottish commissioners who formed part of the Committee of both Kingdoms, asking them for the help of a Scottish army. The more advanced Agitators proposed a still more democratic constitution than The Heads of the Proposals, under the name of The Agreement of the People, and attempted to force it upon their officers by threats of a mutiny. At the same time, they and some of the officers talked of bringing the king to justice for the bloodshed which he had caused. Charles, becoming aware of his danger, fled on November 11 to the Isle of Wight, thinking that it would be easy to escape whenever he wished. He was, however, detained in Carisbrooke Castle, where he was treated very much as a prisoner.
20. The Scottish Engagement, and the Vote of No Addresses. 1647-1648.—Cromwell put down the mutiny in the army, but he learnt that the king was intriguing with the Scots, and at last abandoned all hope of settling the kingdom with Charles's help. On December 26, 1647, Charles entered into an Engagement with the Scottish commissioners. On the condition of having toleration for his own worship, according to the Prayer Book, he agreed to establish Presbyterianism in England for three years, and to suppress all heresy. The Scottish army was then to advance into England to secure the king's restoration to power in accordance with the wishes of a free Parliament, to be chosen after the existing one had been dissolved. The English Parliament, indeed, had no knowledge of this engagement, but finding that Charles refused to accept their terms, they replied, on January 17, 1648, by a Vote of No Addresses, declaring that they would make no more proposals to the king.
21. The Second Civil War. 1648.—The majority of Englishmen were, on the contrary, ready to take Charles at his word. Men were weary of being controlled by the army, and still more of paying the taxes needed for the support of the army. There were risings in Wales and Kent, and a Scottish army prepared to cross the borders under the Duke of Hamilton. The English army had, however, made up its mind that Charles should not be restored. Fairfax put down the rising in Kent after a sharp fight at Maidstone, and drove some of the fugitives across the Thames into Essex, where being outnumbered they took refuge in Colchester. Fairfax, following them up, laid siege to Colchester, though the Londoners threatened to rise in his rear, and a great part of the fleet deserted to the Prince of Wales, who came from France to take the command. In the meanwhile Cromwell suppressed the insurrection in Wales, and then marched northwards. On August 17, with less than 9,000 men, he fell upon the 24,000 who followed Hamilton, and, after three days' fighting, routed them utterly. On August 28 Colchester surrendered to Fairfax.
22. Pride's Purge. 1648.—The army had lost all patience with the king, and it had also lost all patience with Parliament. Whilst Fairfax and Cromwell were fighting, the Houses passed an ordinance for the suppression of heresy, and opened the negotiations with the king which bear the name of the Treaty[26] of Newport. The king only played with the negotiations, trying to spin out the time till he could make his escape, in order that he might, with safety to his own person, obtain help from Ireland or the Continent. The army was tired of such delusions, seeing clearly that there could be no settled government in England as long as Charles could play fast-and-loose with all parties, and it demanded that he should be brought to justice. By military authority he was removed on December 1 from Carisbrooke to the desolate Hurst Castle, where no help could reach him. On December 5 the House of Commons declared for a reconciliation with the king. On the 6th a body of soldiers, under the command of Colonel Pride, forced it to serve the purposes of the army by forcibly expelling all members who took the side of the king. This act of violence is commonly known as Pride's Purge.
